Tree Care Industry Association
Who we are and what we do

The Tree Care Industry Association is a 70-year-old public and professional resource on trees and arboriculture representing approximately 2,100 tree service and affiliated company members. This site has free tree care information and a free zip code search of local tree companies for consumers.

Our members recognize stringent safety and performance standards for quality and safety. They maintain trained, professional arborists on staff and are dedicated to ethics and quality in business practices.

TCIA provides accreditation and certification services for tree care companies and professional arborists. We also provide safety and educational programs, guidelines for tree service operations, ANSI A300 tree pruning standards, and much more.
